Alright, so this has been happening on and off for a few months, but I can't take it anymore. I first noticed this playing League of Legends. When I would leave the client and load into the game, my computer would start lagging horribly and it would stop after the game finally loaded in. The only game I can for sure recreate the issue is Ori and the Blind Forest. As you can see from booting the game my discord voice goes all robotic and my mouse is extremely delayed. In the video I'm doing little circular and side to side motions and it's not fluid like it should be. ALSO, more recently I've been playing Path of Exile and the game runs fine on DX9 but as soon as i switch to DX11 it goes nuts with this problem. Idk if that is any sign of anything but figured i should add.

What I've Tried:
Cleaned inside pc checked cables (nothing looked out of the ordinary)
Used DDU to wipe drivers and reinstall (didn't help)
Ran Memtest86+ (no errors)
Wiped all drives then reinstalled windows (3 times)
Reverted back to Windows 7 (still occurs)
Replaced Thermal paste on CPU
Updated my Bios
Checked HDD & SDD health no signs of error
GPU stress test passed
CPU stress test passed
Ran Combofix / malwarebytes no problems

At this point I'm thinking it's MOBO or PSU but PSU has never shown signs of problems.

I see some strange readings in HWmonitor. Core 3 is reading 94C and core 6 is reading 125C very odd that 2 of your cores are overheating. The were reading around the same even before you opened up the program.
